Liankun Yang 5b195e6f8b drm/mediatek: Add return value check when reading DPCD
[ Upstream commit 5229081406 ]

Check the return value of drm_dp_dpcd_readb() to confirm that
AUX communication is successful. To simplify the code, replace
drm_dp_dpcd_readb() and DP_GET_SINK_COUNT() with drm_dp_read_sink_count().
